MACHINE FOR CREASING STRAPS OF LEATHER.

Specification of Letters Patent No. 10,231, dated November 15, 1853. n

T0 all wiz-0m it may concern Be it known that l, DANIEL H. Hovnr, ofKilborn, in the county of Delaware and State of Ohio, have invented anew and Improved Machine for Oreasing Straps and other Forms of Leatherfor Harnesses and other Purposes; and T do hereby declare that thefollowing is a full and exact description thereof, reference being hadto the accompanying drawings, making part of this specification, Figure1 being a plan of the machine; Fig. 2, a vertical section thereof in theline a; a of Fig. 1, and Fig. 3 an end view of the same.

Like letters designate corresponding parts in all the figures.

Across one end of a table, or bench, A, and raised a little above it, issecured a small bar g; and upon this slide two creasers l1., l1., whichhave their upper adjacent edges Z, Z, sharpened, (as shown in Fig. 3,)to the proper form for creasing the leather, and are provided withshoulders le, 7c, parallel with said edges, and serving to confine thestrap and to limit the distance it is to be creased from its edges.These creasers are forced together by means of springs z', z', attachedto their lower sides and to the table A. Between said springs, behindthe creasers, is situated an oval, or oblong, cam m, which is vibratedon a perpendicular pivot a, by means of a lever p, reaching to one sideof the table. By drawing forward said lever, the cam spreads apart thesprings i, z', and, consequently, the creasers 71 7L, wide enough toreceive the strap to be creased, which having been insertedv betweenthem, the said lever is let free to allow said springs to force thecreasers against the edges ot' the strap.

Above the creasers is situated a horizontal roller c, turning inbearings a, a, which move perpendicularly in guides leading down throughthe table. Said bearings are liept up by springs Z), ZJ, high enough tohold the roller c, as far above the creasers as desired. Their lowerends are connected by a bar, to which is attached a strap CZ, connectingit with a pawl lever e, one end of which is hinged to one side of thetable, and the other end is tree to be pressed down by the root, and isheld in any position by a ratch f, on the opposite side of the table.

The strap to be creased having been inserted between the creasers, asabove described, the roller c, is broughtdown upon it by depressing thelever e; it is then drawn through the machine by the operator, wherebyit is creased at a uniform distance from its edges, however much it mayvary in width; since, if it narrows, the springs z', z', press thecreasers against its edges, and, it it widens, it forces the creasersapart.

Having thus fully described my improved machine for creasing straps,&c., for harnesses and other purposes, what I claim therein as new anddesire to secure by Letters Patent, is-

The combination of the self-adjusting creasers 7L, 7L, springs z', 2',vibratory cam m, and pressure roller c, arranged and operatingsubstantially in the manner and for the purpose herein set forth.

The above specification of my improved machine for creasing straps andother forms o1a leather for harnesses and other purposes signed by methis third day of March 1853.
